Structural characteristics of magnesium rock bead fireproof board

The rock magnesium floating bead fireproof board includes an outer plate, a sandwich plate and an inner plate. The specifications of the outer plate are the same as those of the inner plate. The sandwich plate is arranged between the outer plate and the inner plate. The outer plate is clamped with an outer protective shell on the side away from the inner plate, and the inner plate is clamped with an inner protective shell on the side away from the outer plate. The four corners of the opposite sides of the outer protective shell and the inner protective shell are provided with clamping joints. The outer protective shell, the outer plate, the sandwich plate, the inner plate and the side of the inner protective shell are all provided with through holes. The outer plate includes three matrix plates of the same specifications. The three matrix plates are fixed in sequence by glue. One side of the outer protective shell and at the four corners are fixed with inner hooks. The inner hooks fit the matrix plate. The inner hooks include L-shaped columns and small stickers fixed to each other. The length of the L-shaped column is the same as the total thickness of the three matrix plates.

This type of rock magnesium floating bead fireproof board improves the fire resistance, fire prevention and high temperature resistance of the entire board, improves the board's tolerance at high temperatures, increases the actual service life of the board, and improves the board's anti-extrusion ability, thereby improving the overall practical quality of the board.
